Internals: Not getting floating point correct

Am starting to examine and debug now ... I ran a trace ... and the following is interesting as it appears to clearly show the puzzle. Now going to start looking at jsnative.c:

>var x = setInterval(function() {
:  print("!");
:}, 1000);

  #2[r1,l2] Name String [1 blocks] "ÿ"    #3[r1,l2] Object {

    }
